fs: ufs: use ktime_get_real_ts64() for birthtime

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

CURRENT_TIME is not y2038 safe. Replace it with ktime_get_real_ts64().
Inode time formats are already 64 bit long and accommodates time64_t.
